Description

Technical Field

[0001] The utility model relates to the technical field of metal film processing, in particular to a metal film cutting width adjustment device. Background Art

[0002] Metallized film is a layer of metal film evaporated on the surface of polyester film instead of metal foil as an electrode. Because the thickness of the metallized film layer is much smaller than the thickness of the metal foil, the volume after winding is much smaller than that of the metal foil capacitor.

[0003] In the manufacturing process of film dielectric capacitors, the width of the small film rolls used for winding capacitor cores of different specifications is different. The small film rolls of different widths are cut by a slitting machine from a large film roll into several equal small film rolls suitable for core winding. The working principle of the slitting machine is to cut the large film roll placed on the unwinding arm into several equal small film rolls through several cutting groups and rewind them on the rewinding arm. The spacing between the cutting groups needs to be adjusted to cut small film rolls of different widths.

[0004] The method used in the prior art to adjust the spacing of the cutter groups is as follows: the cutter is fixed on a cutter die of fixed specifications, a plurality of dies provided with cutters are mounted on a die fixing assembly, and the die fixing assembly is mounted on a guide rod. If the spacing of the cutter groups is to be adjusted, it is necessary to replace cutter dies of different specifications or fill spacers of corresponding specifications between the cutter dies, which is not only time-consuming and labor-intensive, but also affects work efficiency and is not conducive to improving product quality.

[0005] Therefore, the existing technology needs to be improved and enhanced. Utility Model Content

[0044] Example:

[0045] like Figure 1-4 The present application provides a device for adjusting the width of a metal film cut, comprising:

[0046] A rotating shaft 100 having a movable end 101 and a knob end 102;

[0047] An adjusting rod 200 having a first end 201 and a first and a second end 202, wherein the first end 201 cooperates with the movable end 101;

[0048] A roller 300 having a shaft body 301, a coil end 302 and a free end 303, wherein the shaft body 301 is movably connected to the second end 202;

[0049] When the rotating shaft 100 moves axially, it can drive the roller 300 to move axially through the adjusting rod 200, so that different positions of the capacitor film installed on the roller 300 correspond to the cutter of the film cutting mechanism, thereby realizing the adjustment of the film cutting width to meet the use requirements of capacitor films of different widths. It not only saves time and effort, but also makes adjustment quick, which helps to improve work efficiency and product quality.

[0050] In a specific implementation of this embodiment, a vertical plate 400 is further included, having a threaded hole 401 and a through hole 402. The rotating shaft 100 is threadedly connected to the threaded hole 401, and the roller shaft 300 is movably inserted into the through hole 402. The middle portion of the adjusting rod 200 is rotatably mounted on a fixing base 500, which is provided on the vertical plate 400.

[0051] When the width of the capacitor film roll mounted on the roll end 302 needs to be adjusted, the knob end 102 of the rotating shaft 100 is rotated clockwise. Since the rotating shaft 100 is threadedly connected to the vertical plate 400, when the knob end 102 rotates, the movable end 101 of the rotating shaft 100 moves away from the vertical plate 400, and the movable end 101 cooperates with the first end 201, so that the first end of the adjusting rod 200 also moves away from the vertical plate 400; since the middle part of the adjusting rod 200 is rotatably mounted on the fixing seat 500, the adjusting rod 200 is 00 moves in the direction close to the vertical plate 400; since the second end 202 is movably connected to the shaft body 301, the free end 303 of the roller 300 moves in the direction close to the vertical plate 400, that is, the coil end 302 of the roller 300 moves in the direction away from the vertical plate 400. Conversely, rotating the knob end 102 of the rotating shaft 100 counterclockwise makes the coil end 302 of the roller 300 move in the direction close to the vertical plate 400, so that different positions of the capacitor film correspond to the cutter of the film cutting mechanism, thereby completing the adjustment of the film cutting width.

[0052] As a preferred embodiment of this embodiment, a dial 403 is provided on one side of the vertical plate 400 close to the knob end 102, and the dial 403 is movably mounted on the rotating shaft 100. By setting the dial 403, the user can intuitively adjust the change amount of the rotating shaft 100.

[0053] Specifically, the first end 201 abuts against the movable end 101. Of course, the first end 201 can also be hinged to the movable end 101.

[0054] Specifically, the second end 202 forms a spherical connection with the shaft body 301, the second end 202 has a spherical connection portion 2021, the shaft body 301 has a spherical connection groove 3011, and the spherical connection portion 2021 is rotatably fitted in the spherical connection groove 3011. Therefore, when the second end 202 approaches or moves away from the vertical plate 400, the roller shaft 300 correspondingly moves away from or approaches the vertical plate 400.

[0055] Specifically, a sleeve 304 is provided on the side of the vertical plate 400 close to the free end 303, and the sleeve 304 is movably sleeved on the roller shaft 300. A movable groove 3041 for the movement of the adjusting rod 200 is axially provided on the side of the sleeve 304 close to the adjusting rod 200. When the roller shaft 300 moves axially, the adjusting rod 200 moves axially along the movable groove 3041.

[0056] Specifically, the free end 303 is provided with a limit plate 305, and a spring 306 is sleeved on the roller shaft 300 between the limit plate 305 and the sleeve 304. In this embodiment, since the first end 201 is in contact with the movable end 101, when the knob end 102 of the rotating shaft 100 rotates counterclockwise, the movable end 101 always maintains contact with the first end 201 under the action of the spring 306.

[0057] As a preferred embodiment of this embodiment, a guide column 307 is provided on the roller 300, and a guide groove 3042 is provided on the outer wall of the sleeve 304 along the axial direction. The guide column 307 performs linear reciprocating motion in the guide groove 3042. The movement trajectory of the roller 300 is guided by the cooperation between the guide column 307 and the guide groove 3042, ensuring that the roller 300 moves according to the predetermined path.

[0058] like Figure 5 As shown, it is a metal film cutting machine, wherein A is the first metal film unwinding mechanism, B is the second metal film unwinding mechanism, C is the slitting mechanism, and D is the winding mechanism; when the present application is applied to the metal film cutting machine, they are respectively arranged beside the transmission path of the first metal film A1 and the transmission path of the second metal film B1. When it is necessary to adjust the width of the first metal film A1 and / or the second metal film B1, the roller 300 is moved axially by adjusting the knob end 403, so that different positions of the capacitor film correspond to the cutter of the film cutting mechanism, thereby completing the adjustment of the film cutting width.
